As you use 1.1.1.1 in your infrastructure or service, note that dedicated technical support is limited.
You are subject to the Cloudflare Website and Online Services Terms of Use ↗ and no service level agreements (SLAs) are provided.
If you need SLAs and dedicated support, consider using Cloudflare Gateway instead. Gateway adds policy-based DNS filtering and management.
Gateway includes other advanced options such as domain categories, customized filtering, and scheduling capabilities. For example, if you are a device manufacturer or network operator, you can use a multi-tenant environment — where a single deployment serves multiple separate customers — to allow your customers to configure their own individual filters.
